Actual Steps to Cancel SoftBank Hikari's "Ouchi Wari Hikari Set"

At my home, I was applying the "Ouchi Wari Hikari Set" with Y!mobile (Y!mobile) and SoftBank Hikari, but
This time, I decided to stop using Y!mobile, so the options required to apply SoftBank Hikari's "Ouchi Wari Hikari Set" became unnecessary.
I will introduce the actual steps to cancel these options with screenshots.

(First of all) About the "Ouchi Wari Hikari Set"
The "Ouchi Wari Hikari Set" is a service that discounts your smartphone bill by 1100 yen every month when you combine "SoftBank Hikari" with a "smartphone (SoftBank or Y!mobile)".

To apply this "Ouchi Wari Hikari Set", you need to subscribe to the following essential SoftBank Hikari options.
- Hikari BB Unit Rental
- Wi-Fi Multi Pack (or Wi-Fi Terrestrial Digital Pack)
- BB Phone (or White Hikari Phone or Hikari Phone)
For SoftBank Hikari 10 Gigabit, "Hikari BB Unit Rental" is not required, so please read accordingly.
Combining these three options costs 550 yen per month.
So, even though the smartphone bill is discounted by 1100 yen, it's effectively a 550 yen discount.
This time, I will continue to use SoftBank Hikari, but since I stopped using Y!mobile, I will cancel these three options.
Notes before cancellation
When canceling, the following points should be noted:
- If using Wi-Fi, your own Wi-Fi router is required
- Prepaid return of rental equipment is required
- (If using a landline phone) Be careful when canceling BB Phone
I will briefly explain each point.
1. If using Wi-Fi, your own Wi-Fi router is required
Currently, you are probably using Wi-Fi at home, but if you are using Wi-Fi with the Hikari BB Unit (and do not have your own Wi-Fi router), you will need to purchase a Wi-Fi router.
This is the Hikari BB Unit.
If you are using Wi-Fi with this,
You will need your own Wi-Fi router like this.

This is the model I use at home.
If you are not too concerned about speed, a model in this price range is also fine.

Also, to use a commercially available router with SoftBank Hikari, initial setup is required. Here are some reference URLs.

2. Prepaid return of rental equipment is required
※This is probably not required for SoftBank Hikari 10 Gigabit.
If you cancel the "Hikari BB Unit Rental" option, you will need to return the "Hikari BB Unit".
This is the Hikari BB Unit.
Since prepaid return is required, please expect shipping costs to be just under 1000 yen.

3. Notes on canceling "BB Phone" are limited to those who use a landline phone. I will omit them here.
Option cancellation procedure
Access My SoftBank and log in to SoftBank Hikari.
From the "Services" tab, open "Change" for "Hikari BB Unit Rental".
Notes and other information will be displayed, so tap "Change/Stop" at the bottom.
Check all options to cancel.
Here, it's the three items: "Hikari BB Unit Rental", "Wi-Fi Multi Pack", and "BB Phone".
Tap "Confirm" at the bottom
Check "Apply for connection method change cancellation" and tap "Confirm"
(The Japanese is a bit confusing, but check this box if you want to cancel)
Agree to the terms and tap "Confirm"
On the next screen, tap "Apply".
With this, the cancellation procedure is complete.
Next, we will proceed with returning the rental equipment.
Returning the equipment (prepaid)
I apologize for not having specific photos as I forgot to take them, but
You need to send the "Hikari BB Unit" back to SoftBank.
Pack it in a suitable cardboard box and send it to SoftBank via Yamato or Yu-Pack, etc.
Please note that NTT equipment does not need to be returned.

After returning the equipment and SoftBank receiving it, the options were removed in 2-3 days.
All's well that ends well.
